A low-field Nuclear Magnetic Resonance dataset of whole milk during coagulation and syneresis

Abstract

We report the relaxometric dataset obtained on renneted milk during syneresis by Time-Domain Nuclear Magnetic Resonance spectroscopy (TD-NMR). Data were obtained on cow's milk provided by two different producers in two different lactation seasons (April and October) and on a group of goat's milk samples (one season, November–December, one producer). TD-NMR data refer to spin-spin relaxation times (T2) decay curves and distributions measured at 40 °C at seven time points after rennet addition, up to 70 minutes of syneresis. Curd was cut 30 min after rennet addition without removing the NMR tube from the TD-NMR instrument. The dataset here reported is related to the research article entitled “Non invasive monitoring of curd syneresis upon renneting of raw and heat-treated cow's and goat's milk” [E. Curti, A. Pardu, S. Del Vigo, R. Sanna, R. Anedda, Non-invasive monitoring of curd syneresis upon renneting of raw and heat-treated cow's and goat's milk, Int. Dairy J. 90 (2019) 95–97].

Non-destructive control in cheese processing: Modelling texture evolution in the milk curdling phase by laser backscattering imaging

“…In addition, these devices limit the development of other online applications in the cheese production chains, such us curd cutting applications (O'Callaghan et al, 2002). In this sense, several non-destructive applications have been developed for curdling process characterization, which are based in different principles such us ultrasounds (Jiménez et al, 2017), optical techniques (Arango & Castillo, 2018;Castillo et al, 2005;Mateo et al, 2010) , nuclear magnetic resonance (Curti et al, 2019) and different image analysis procedures (Darnay et al, 2017). Within image analysis procedures, the laser-backscattering imaging characterizes the extinction of light transmittance across a changing magnitude measured in a given matrix.…”
